Factores que influyen en la embriogénesis somática in vitro de palmas (Arecaceae)
(2011-12)
La embriogénesis somática (ES) es una vía de desarrollo in vitro que presenta una serie de ventajas sobre otras técnicas utilizadas para la regeneración de palmas. Esta técnica tiene gran potencial para superar las ...
Improved high-efficiency protocol for somatic embryogenesis in Peach Palm (Bactris gasipaes Kunth) using RITA® temporary immersion system
(2014-11)
Bactris gasipaes Kunth (Arecaceae) is an Amazonian palm cultivated mainly for the production of fruits and heart of palm. Biotechnological tools based on somatic embryogenesis (SE) can be used for improvement and germplasm ...
Ultrastructure and histology of organogenesis induced from shoot tips of maize (Zea mays, Poaceae)
(Rev. biol. trop vol.57 supl.1 San José nov. 2009, 2009-11)
Shoot tips of maize (Zea mays L.) were cultured on Murashige and Skoog medium supplemented with 2 mg/l BA +1 mg/l 2,4-D +40 mg/l, to investigate phases of ontogenetic development. The study used light microscopy as well ...
Responses of Arabica coffee (Coffea arabica L. var. Catuaí) cell suspensions to chemically induced mutagenesis and salinity stress under in vitro culture conditions
(2018)
Crop improvement of Coffea arabica L. (coffee) via mutagenesis could accelerate breeding programs; thus, the present study aimed to develop an in vitro protocol using the chemical mutagens sodium azide (NaN3) and ethyl ...
Comparision of three in vitro Protocols for Direct Somatic Embryogenesis and Plant Regeneration of Coffea arabica L. CVS. Caturra and Catuaí
(Agronomía Costarricense, vol. 31, n. 1, 2007, 2007)
Comparación de tres protocolos para la embriogénesis somática directa y la regeneración de plantas de Coffea arabica L. cvs. Caturra y Catuaí in vitro. La presente investigación tuvo como objetivo establecer una metodología ...
Heterogeneidad clonal en epimastigotos de una cepa centroamericana de Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae)
(2002)
El fenómeno de heterogeneidad clonal fue evaluado en una cepa centroamericana de Trypanosoma cruzi (San Salvador) en un sistema de cultivo en macrófagos. Cuatro clones denominados Clon 9, Clon 10, Clon 11 y Clon 12 fueron ...
In vitro propagation of purple pitahaya (Hylocereus costaricensis [F.A.C. Weber] Britton & Rose) cv. Cebra
(2012-10)
Limitations to large-scale propagation of purple pitahaya (Hylocereus costaricensis [F.A.C. Weber] Britton & Rose), a potential source of betalains for the food industry, can be overcome through utilization of in vitro ...
In vitro propagation of bamboo species through axillary shoot proliferation: a review
(2017)
Bamboos, very relevant plants in many countries around the world, are propagated at large scale with extreme difficulties. Use of seeds is challenging because of plant’s sporadic flowering and long flowering cycles, together ...
Determinación del crecimiento de hongos nematófagos en diversas fuentes de carbono
(2015)
Las enmiendas orgánicas han sido utilizadas para estimular la acción antagónica de los hongos nematófagos depredadores (HND) del suelo, sin embargo, su uso ha producido resultados inconsistentes en el control de nematodos ...
Effects on cultured mammalian cells of myotoxin III, a phospholipase A2 isolated from Bothrops asper (terciopelo) venom
(1993-11)
Myotoxin III (MT-III), a myotoxic phospholipase A2 from Bothrops asper, was studied with respect to interactions with cultured mammalian cells and red blood cells. Tests of the cytopathogenic effect of MT-III on different ...
